Investigation of Rubidium Hyperfine Structure Frequency Stabilization Mechanisms

摘要

The linewidth and frequency associated with the ground state hyperfine energy for Rb 87 has been studied. A stable single mode semiconductor laser is used to optically pump Rb. in order to obtain a highly collimated, monochromatic light source. The laser is stabilized by locking its optical frequency to the Rb absorption line center. The dependence of the hyperfine frequency and resonance linewidth have been measured as a function of temperature, light intensity and microwave power; and a theoretical description of the linewidth vs. temperature data is presented.
